I know the season pass and leveling up is broken, but they made it even worse with the 2xp timer.
You have 5 mins left? Sorry, wasted. You cannot use another and it will time out before next games ends.
You didn’t get that challenge? Sorry, 2xp wasted.
They included xp boosts because, um… Isn’t that what you’re supposed to do? Unfortunately, no one spent even a second to think how easy it would be to waste them with this system.
Pretty much what BlueDevistator said. With the system we have now, you’ll need to strategize what challenges you plan to tackle before popping the boost. Still a silly system if I might add, but that’s the smartest way to utilize boosts.
Rather than time, XP boosts should really be for a number of matches, exactly for that reason. Some matches take longer than others, so you have no idea if you’re going to have enough time.
